T0 (1! whom may concern:

"fulcrum with pics or projections eudD fil Patented Feb. 6, 1906.

adopted to alternately engage opposite sides of alever-F, mounted to swing on the shaft E as a fulcrum and provided at its upper end -with a weight F. The lower end of the weighted lover F engages on elon cted slotG in a link G, connected with the stem 1:? of a valve H, adapted to be seated on cseat H, arranged within a valve-casing H secured t the casing A and extending at the outside thereof, as plainly illustrated in the drawings. The outer end of the valve-casing H is -pro vided with an apcrtured cop H opening to the atmosphere; and on the stenrl'l is socured or formed a piston H mounted to slide in suitable hearing formed on the casing il so as to prevent the liouid within the cas ing A from passing into the valve-cas1ng H. The latter is provided with two chambers H and H separated from each other by the valve-scat H the chamber H" being in communication with the outer air by the apertured cap II. From this chamber H leads a pipe l to the chamber J of o diaphragm-cas- J, containing a diaphragm J pressed on its outer face by the atmosphere, the inner face. which extends within the chamber J,'

being pressed on by a spring J A stem J is secured to the diaphragm J and extends through a valve-casing K, connected by a pipe L with the interior of the casing A at or near the top thereof, the said valve-casing K being also connected by a pipe N with a suitable steamsupply, such as a boiler, and by a pipe 0 with the. top of a vacuum-producing device of any approved construction.

The valve-casing K is provided with valvcseats K and K", on which are adapted to be seated valves J and J, held on the diephregm-stem J, thearrangement being such that when one valve is seated on its seat the other is oil its seat, and vice verse. As shown in Fig. 1, the valve-seat K is intermediate the pipes N and L, while the valve-seat K is intermediate the pipes O and L, and when the several parts are in the position shown in Fig. 1 and the valve J is on its seat K and the valve 5 is oil its soot K" then the steam under pressure can pass by Way; of-the pipe N, the valve-casing K, and pipe i to the upper end of the casing A to pr'ess'on the liquid contained therein and force the said liquid out through the valved pipefl to a suitable plac s of discharge. jtion-of the valve J and J is reversed-dhdt is, When the valve 5 moves onto its seat K and the valve J moves oil its seat K -then When the posiifloat D falls with the falling water, and in the va ve H is at the same time units seat- H then atmospheric pressurepa'ssir'i throu h the cap H, chamber H9, and pipe into t echamber J counterbalances the atmospheric pressure on the outside of the diaphragm J so that the spring J holds the valve J in a closed osition and the valve J open. When the va ve H is opened, it closes the aperture in the cap H, (see Fig. 4,) and communication is now established between the Cl'lfllIl-' bers H and H by way of the valve-seat H so that air is drawn from 'the cha I ber J by way of the pipe 1, chamber H, va ve-seat H chamber H pipe P, valve-casing K, and pipe 0 to cause the atmospheric pressure on the outside of the diaphragm J 2 to move the latter, and with it the stem J and valves J and J for the valve J to move onto its seat K and the valve J to move off its seat K The operation is as follows: When the float-lever D and the weighted lever F are moved from the position shown in Fig. 4 into the position .shown in Figs. 1 and 2 by the rising water accumulating in the casing A, then the steam enterin the casing A by way of the pipe N, open va ve-seat K casing K, and pipe L forces the water out through the pipe C to a placel of discharge, and durin the time the water passes out of the casing the doing so the lever D finally assumes the position showln in Fig. 3that is, the pin D engages one side of the weighted lever F. As the water still passes out of the -easing A the float D falls farther downward, and'in doing so causes the lever D to impart a swinging motion to the lever F by the pin D", so that the lever F is finally moved into and past a vertical position to then swing suddenly downward by the action of its weight F to shift the link G, and with it the valve-stem H and valve H, for the several parts to assume the position shown in Fig. 4. When this takes place, the diaphragm-chamber J is closed to the atmos here and connected with the vacuumpro ucing apparatus, as previously explained, so that the diaphragm J 2 is actuated and causes the valve J to move onto its seat K and the valve J to move off its seat K Thus the steam is shut off from the casing A and the interior thereof is connected with the vacuum-producing apparatus, so that avacuum is produced in the casing A to allow the Water of condensation to flow from the vacuum apparatus by way of the pipe B into the casing A to accumulate therein. As the water accumulates in the casing A the float D is caused to rise, thereby impartin a. return. swingingmmotion to the lever D, w ich by its pin- 3 ally engages the lever F to swingthe same backinto a vertical. and past a 'ver tical position for the lever F to then complete its return stroke. The lever F in doing so pulls on the link G, thereby moving the valve-stem H and the valve H in an inward direction for the valve H to be finally seated on-its seat H When this takes place, the chamber J is disconnected from the vacuum-producing apparatus and is again connected with the atmos here, thus allowing the spring J to move t e diaphragm J "outward, and consequently to return the valve J to its seat K and to move the valve J off its seat K to again admit steam to the interior of the casing A, and the above-described operation is then repeated;

From the foregoing it will be 'seen that the vacuum produced'in the casing Acorresponds to that in the vacuum apparatus to -.'be

drained-of the liquid, so that the liquid can flow from the vacuum apparatus by way of the pipe B into the casing A, and when a change in the valve mechanisms takes place by the action of the rising water on the float D and its lever D then'steam is admitted to the casing A to force the accumulated water out of the casing to a suitable place of discharge. The steam entering the casing Aiis prevented from flowing into the vacuum a paratus by way of the pipe B, owing to the check-valve B, contained in the said pipe B.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A vacuum-trap having a casing for the accumulation of the liquid, a connectionwith a pressure-supply and a vacuum apparatus, a valve mechanism in the said connection, for alternately connecting the casing with the. pressure-supply and the vacuum apparatus, a fluid-pressure device for actuating the said valve mechanism, and a float-controlled valve for alternately connecting the said. fluid-pressure device with the said vacuum apparatus and the atmosphere.

2. The combination with a casing, of a valve mechanism, a float-lever carrying a floatdacted on by the liquid accumulating in the casing, the said float-lever being provided with projections on the same side of the lever at opposite sides of its fulcrum, a weighted lever mounted to swing on the fulcrum of the float-lever, and extending between the said projections on the float-lever, the said projections being adapted to alternately engage opposite sides of said weighted lever, and a slotted link engaged by the said weighted lever and connected with the said valve mech anism.

The combination with a device to be controlled, of a weighted lever connected 1- 0 engage opposite sides of the said weighted with the said device, and

a float-lever carrying a float, and provided with two projections located at opposite sides of the fulcrum, the sand projections being adapted to alternately lever.

4. The combination with a diaphragm-we ing, and aspiring ressed diaphragm therein,

of a valve-casing aving connection with the apparatus to be controlled, a connection with a pressure-supply, a connection with a vacuum-producing device, and valves con trolled by the said diaphragm, for alternately connecting the sa1d\apparatus connection with the pressure-supply and the vacuumproducing apparatus.

5. The combination with a diaphragm-casing, and a spring-pressed diaphragm therein, of a valve-casing aving connection with the apparatus to be controlled, a connection with a pressure-supply, a connection with a vacuum-producing device, valves controlled by the said diaphragm, or alternately connecting the said apparatus connection with the pressure-Suppl and the vacuum-producing apparatus, an a float-controlled valve having connection with. the pressure side of the diaphragm and with the said vacuum connection.
